LAYERED HEAT-DISSIPATION LIQUID COOLING CABINET

A layered heat-dissipation liquid cooling cabinet is disclosed including a cabinet, layered racks, and a plurality of liquid cooling components. A plurality of modules are plugged into each layered rack. The layered racks are vertically distributed in the cabinet. A plurality of the liquid cooling components and the layered racks are distributed apart. Each layered rack is arranged into a frame structure with openings at two ends. The top of the layered rack is provided with ventilation holes. Gap grooves are provided between adjacent modules in the layered rack. A perforation is provided on a bottom inner wall of each gap groove. Heat gas between different layered racks is separated to prevent heat overload caused by concentration of overall heat in the cabinet on a top end thereof and enable the perforations to be communicated up and down when a region where a layered rack is overheated due to operation.
